Parafavella in cell division

Parafavella parumdentata in the process of cell division. The uppermost halve, the protor, will have the parental mouth and swim away to form a new lorica. The lower halve, the opisthe, is still forming its mouth. It will remain, inheriting the lorica. Specimen from the Northern Pacific, Station 9 of the Shippo 2012 cruise. Z-stack of images made using a 40x objective and DIC optics.
